Abstract:
A furfuryl alcohol derivative having the general formula X[—CH(OR)]is prepared by an aldehyde with a furfuryl alcohol in the presence of a copper catalyst. In this formula, X is an aliphatic, cycloaliphatic, aromatic or araliphatic group, R is a 2-furyl group, 2-(5-methylol) furyl group or a mixture thereof, and m is in the range of from 1 to 5. Reaction conditions allow a product having less than 25% free furfuryl alcohol, providing a composition that is suitable as a binder for foundry aggregate in producing a foundry mix.
